This utility model relates to the field of medical device technology and discloses a quick-adjustment buckle for a patient limb fixation strap during CT examinations. It includes a strap body with a T-shaped groove at its top. A T-shaped slider is slidably connected to the inner wall of the T-shaped groove, and the top of the T-shaped slider is fixedly connected to the bottom end of the elastic fixation strap. This utility model adjusts the position of the elastic fixation strap by sliding the T-shaped slider within the T-shaped groove, ensuring the elastic fixation strap roughly covers the limb area requiring fixation. Then, a locking pin is engaged with a suitable limiting fixation hole. When selecting the limiting fixation hole, consideration should be given to ensuring both effective fixation of the patient's limb and patient comfort. The magnetic buckle is then engaged with the locking pin to complete the fixation of the patient's limb. At this point, the elastic wristband pad contacts the patient's limb, and the elastic fixation strap generates appropriate elasticity according to the shape and condition of the patient's limb, ensuring both stability and comfort.
